CADET GUN AND RIFLE.

To all whom it may concern:

lie it known that we, EDWARD l1. TIFFANY and FREDIHCK S. Looms, citizens of the.

United States, and residents of the'city of Hoboken, county of Hudson, Jersey, have invented certain new and useful Improvements in Cadet Guns and Rifles, of which the following is a specification.

Our invention relates to improvements in cadet guns or rifles'in which a cylindrical gun chamber is so constructed that only blank cartridges may be inserted into its bore, and also to prevent pieces of extracted bullets or pieces of a cartridge torn off by the force of'the powder when the gun is discharged-a0 be carried through the barrel. and the object of our invention is to construct a gun or rifle for cadets, for use on stages, etc, which maybe discharged for effect of detonation only, without danger that a stray missile may imperil the safety of bystanders. \Ve attain this object by the mechanism illustrated in the accompanying drawing in which:

Figure l is a partial sectional side elevation of a gun. showing the arrangements Fig. 2- is a longitudinal section of a portion of a gun showing the parts of the invention as arranged in the barrel of same. Fig. 3- is a cross section on line 3, 3 in Fig. 2. Fig. 4-

Fig. 5 is a front elevation of same. Fig. 6- is a side elevation of a modification of the gun chamber shown in Fig. 4. Fig. 7-- is a front elevation of same.

Similar letters refer to similar parts throughout the several views.

The gun A has a barrel B, in which is inserted a cylindrical gun chamber D fastened therein by a screw J. From one end M of said gun chamber D a longitudinal boreE, similar in length and diameter to a blank cartridge, extends inwardly to a point F and thence angularly toward the other end N a stationary metal Near said end block H is secured to the inside of the gun barrel B to prevent any missile carried out of the gun chamber D by the force of the powder. from passing through the gun barrel B. A modification of said D is shown in Figs. 6 and 7 where a longi- Specification of Letters Patent.

tudinal bore E similar in size to a blank cartridge extends to a smaller sized bore F. The connection of a longitudinal bore similar in size to a blank cartridge with a smaller sized bore or with an angular one will prevent an insertion of a cartridge charged with a bullet.

The gun chamber D, constituting a short cylinder of the same diameter as the gun barrel B, is provided. with a straightand an angular bore E and F it is inserted into the gun barrel B and fastened therein by a screw J. Said gun barrel B maybe a thin tube of steel or it may be stamped out of sheet metal. bent and welded to form a permanent union steel tubing. The arrangement of havinga gun chamber fastened into a tube will greatly reduce the cost of manufacturing a gun. as the barrels of the guns now used by cadets have to be bored the whole length. .Ve prefer to carry out this feature of our invention in the manner gunchamber (D) secured to the barrel (B) supported by the stock L. The former is provided with a blank cartridge (G). The missile catching block H is placed near the front of said gun chamber and the firing pin C in back of the gun chamber is ready to ignite the same. when pulling the trigger K.

hat we claim as our invention and desire to secure by Letters Patent is:

A cadet gun having a shoulder stock, a tiring means and a tubular barrel. in comhination with a removable cart-ridge. holding member incapable of receiving a hall cartridge interposed between said tiring means and said barrel. said member having a laterally inclined passage-way communicating with the interior of said tubular barrel. an obstructing member in the barrel in advance of the cartridge holding member. with provision for the passage of gases as shown and described.
